President Trump threatened yesterday to cut off aid to any country that votes today against the U.S. decision to recognize Jerusalem as Israel’s capital. The takes place today at the emergency special session being convened at the United Nations General Assembly, called for by Turkey and Yemen (via Iran).

This vote follows the announcement of Dec. 6, when Trump fulfilled his campaign promise to recognize Jerusalem as the capital of Israel and directed the State Department to begin the process of moving the U.S. embassy there. But more than that, Trump’s recognition acknowledges the underlying problem of the past 30 years of diplomatic efforts: recognizing reality.
